It'd be great to be able to drag emails to a sidebar that becomes a 'to do' list... I've made a folder but a sidebar (with an option to hide) is better ;)

Often emails are related even though in different threads. The ability to link threads somehow would be very useful.

when i share a document Airmail 3 won't connect even when set ad default

I thought that I had been deleting emails when I sent them to trash and then emptied the trash. Unfortunately it looks like Airmail is somehow archiving ALL email even after it's been deleted. I just found gigabytes of old email that I thought had been permanently deleted. You can test this by doing a search for old email that otherwise should have been deleted. Seriously this is a deal breaker. There MUST be a way to permanently delete email instead of archiving it forever.

A notification that mail to recipients in CC and BCC has been read.

I'd be very happy to have 2 different tones (dark and bright) on Airmail depending on the hour of the day...
BlueMail offers this already. It's a blessing to read email early morning without wearing sun glasses:)

We have a policy at work not to auto collect email addresses to prevent the autocomplete/user to make the mistake of sending the email to johndoe@thenewyorktimes.com instead of johndoe@client.com.
We fill the address book with only internal addresses so mistakes stay within the company.

So the only way we are allowed to use airmail is if we can prevent the collection of addresses.
Please make it an option which we can disable.

Currently when marking all messages as read in a folder the user is prompted for confirmation. It would be useful to have the option of disabling this confirmation step.

Please add Touch Bar and Touch ID support for latest 2016 Macbook Pro models, that would be awesome.

It would be great if you included the ability to support antivirus scanning engines for mail attachments.

What would be even more awesome is if you supported something even more powerful like a milter interface so that airmail could leverage a "standard" api to have email processed by a secondary applications:

If you are looking at a message in a smart folder, you can't archive it. You should be able to.

Hello.
I very like AirMail, but I wish to more integration with inbox by Google. New features like: reminders or visible options from inbox like "links"

I suggest some enhancements to keyboard shortcuts for navigating conversations. This would complement the 'n' and 'p' navigation options that already exist.

';' to expand all messages in the conversation

':' to collapse all messages in the conversation, except the most recent.

'x' or '<space>' to toggle expansion of the currently selected message
- same as clicking on the Subject line does

I think Airmail is a great client & it has been a lifesaver since my employer switched to o365.

Thanks!

Archive a conversation in a group email to automatically archive future responses to the same thread.

I can rebuild a whole account so that all messages are re-downloaded. This is good but not very practical when there is a lot of messages in that account, so I'd like to be able to rebuild just one folder or mailbox.

Search history. I want Airmail to remember past searches as a dropdown list as I start typing a search. In the same day I will often repeat the same search. As I switch views I lose my search and have to go back and re-create it. This is particularly true because I cannot have multiple inbox windows (will request separately).
